Dibutyl ether and 1 -butene can be formed as by products in this reaction. explain how they are removed by sulfuric acid. Give the reactions
The equilibrium constant for CaCO3 dissolution in water at 25 celsius is 8.7 x 10^-9. Calculate the (G) Gibbs free energy for this process.
A mixture of N2, O2, and CO2 has a total pressure of 791. torr. In this mixture the partial pressure of N2 is 115. torr and the partial pressure of O2 is 193. torr.
Identify the mass spectral (MS) peaks you would expect for 4-Heptanone (M+ and m/z for all fragments). Just FYI, the professor said
Calculate the values of E for the cell when the following volumes of the Ce^4+ titrant have been added. (Activity coefficients may be ignored as they tend to cancel when calculating concentrations of ratios.
A student mixed 75.0 mL of water containing 0.75 mol HCl at 25 degrees C with 75.0 mL of water containing 0.75mo of NaOH at 25 degrees in a foam up calorimeter. The temperature of the resulting solution increased to 35 degrees C.
These 3 solutions including 2.362 g of Rb2S, 1.635 g of NaClO 4 , and 0.796 g of CuCl 2 , respectively are combined together? now calculate what would be the mass of this precipitae?
Within this analogy, discuss how the shielding by core electrons is analogous to putting a frosted-glass lampshade between the lightbulb and your eyes, as shown in the illustration.
A piece of metal of mass 22 g at 92C is placed in a calorimeter containing 53.7 g of water at 21C. The final temperature of the mixture is 55.3C. What is the specific heat capacity of the metal?
What mass of grams of KNO3 will crystallize out of solution if exactly 475.0 g of its saturated solution at 75 celsius is cooled to 25 celsius?
If 3.0 Ml of distilled water is added to 2.0 ml of 0.35M CoCl2 solution, what is the concentration of the resulting solution.
Write equations to show how nitronium ions might be formed using a mixture of nitric and sulfuric acids
As a technician in a large pharmaceutical research firm, you need to produce 350.mL of 1.00 M potassium phosphate buffer solution of pH = 6.87. The pKa of H2PO4- is 7.21.
